Hinweise

Standardmäßig berücksichtigt die Auflistung die Groß-/Kleinschreibung und verwendet die Implementierung des Object.GetHashCode Schlüssels von als Hashcodeanbieter und die Implementierung des Object.Equals Schlüssels von als Vergleich.

Der Vergleich bestimmt, ob zwei Schlüssel gleich sind. Jeder Schlüssel in einem HybridDictionary muss eindeutig sein.

Dieser Konstruktor ist ein O(1)-Vorgang.

HybridDictionary(Boolean)

HybridDictionary.cs
Quelle:
HybridDictionary.cs
Quelle:
HybridDictionary.cs

Erstellt ein leeres HybridDictionary mit der angegebenen Berücksichtigung der Groß- und Kleinschreibung.

public:
 HybridDictionary(bool caseInsensitive);
public HybridDictionary (bool caseInsensitive);
new System.Collections.Specialized.HybridDictionary : bool -> System.Collections.Specialized.HybridDictionary
Public Sub New (caseInsensitive As Boolean)

Parameter

caseInsensitive
Boolean

Ein boolescher Wert, der kennzeichnet, ob beim HybridDictionary die Groß- und Kleinschreibung berücksichtigt wird.

Hinweise

Wenn caseInsensitive ist false, verwendet die Auflistung die Implementierungen des Schlüssels von Object.GetHashCode und Object.Equals. Wenn caseInsensitive dies der Fall ist true, führt die Auflistung einen einfachen Ordinalvergleich ohne Beachtung der Groß-/Kleinschreibung durch, der nur den Groß- und Kleinschreibungsregeln der invarianten Kultur gehorcht.

Parameter

Int32

Die ungefähre Anzahl von Einträgen, die die HybridDictionary anfänglich enthalten kann.

Hinweise

Wenn die anfängliche Größe der Auflistung größer als die optimale Größe für ein ListDictionaryist, wird die Auflistung in einem Hashtable gespeichert, um den Mehraufwand beim Kopieren von Elementen aus dem in den ListDictionaryHashtablezu vermeiden.
